Method of manufacturing an insulation substrate

摘要

Disclosed are an insulation substrate comprising:
a conductive pattern that is provided on a surface of a ceramics substrate, wherein, of an external surface of a conductor constituting the conductive pattern, a rising surface that rises from the surface of the ceramics substrate substantially rises vertically with respect to a direction along the surface of the ceramics substrate, the conductive pattern is joined with the surface of the ceramics substrate by a brazing filler metal, and at least a lower part of the rising surface of the conductor in a direction in which the rising surface rises from the surface of the ceramics substrate is covered with the brazing filler metal,
a method for manufacturing an insulation substrate and
a power module comprising said insulation substrate.
